Patented Sept. 11, 1906.

To all whom it may concern.-

' Be it known that I, H RBERT A. SILVERA, a citizen of the UnitedStates, residing at the city of New York, in theboroughof Brooklyn,county of Kings, and State of New York, have invented certain new anduseful Imrovements in Disinfecting Apparatus; and

do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertainsto make and use the same.

My invention relates generally to disinfecting, fumigating, ordeodorizing apparatus, and particularly to apparatus designed to be usedin connection with a flush-tank or the like for impregnating the waterin said tank with a disinfecting, deodorizing, or odor-disguisingsubstance. V

My invention consists in means whereby when the tank fills a measuredquantity of the material'tobe used in im regnating the water in the tankis discharged therein.

The objects of my invention are to impregnate the water in flush-tanksand the like with asuitable disinfecting, deodorizing, orodor-disguising substance, to avoid unneces sary waste of the substanceso em loyed for .impregnatin the water, and to ma 'e the apparatus empoyed simple, reliable, and relatively inexpensive.

I will now proceed to describe my inven- V tion with reference to'theaccompanying drawings, in which certain forms of apparatus embodying myinvention are illustrated, and will then pointout the novel features inclaims.

In the said drawings, Figure 1 shows a vertical section of one form ofmy apparatus as ap lied to a flush-tank. Fig. 2 shows a centralongitudinal section of the valve of such ap aratus on a larger scale.

eferring now to the drawings, I have shown my invention as applied to anordinary" fiush-tank such as is commonly used with sanitary apparatusand which is provided with a conventional form of dischargevalve 2 andwith a float-operated inlet-valve 3. The disinfecting or other materialis commonly contained within a closed vessel 4., usually placed aboveand over the tank 1 and havin in its bottom a discharge-valve 5,eperated by a float 6 and arranged each time the tank fills to dischargea measured quantity of the disinfecting material into the water in saidtank. This valve may have various forms and constructions. In theconstruction shown in Figs. 1 and 2 it consists of a hollow cylinder,both ends of which are closed, the interior of the valve constituting,1n effect, a measuring-chamber arranged to receive at each operation adefinite quantity of the disinfecting material and in the nextsucceeding operation to discharge its load into the water in tank 1. Forthis urpose the valve is arranged to slide vertical y within aguide-bushing 7 and is provided with two ports 8 and 9, the formerlocated near the top of the internal chamber of the valve, the iatterlocated near the bottom of said cham- In the elevated. position of thevalve port 8 is in communication with the interior of vessel 4 and port9 is closed by bushing 7, while in the opposite position of said valveport 8 is closed by the bushing 7 and port 9 is open.

The operation of this apparatus will be understood readily. Upon theopening of the discharge-valve 2 of tank 1 the water-level in the tankwill fall rapidly, and as it falls the valve 5 will open, dischargingits disinfecting material into the tank. During the subsequent fillingof the tank the float 6 will lift the valve 5,.thus' causing port 8 toopen, so that the valve again fills and remains filled until throughfall of the water-level in tank 1 port 9 is opened and port 8 closed.The valve 5 slides freely through the bushing 7, but nevertheless formsa sufficiently tight joint therewith to prevent leakage. It will beobserved that the vessel '4 is never in communication with the outerair. Each'time the chamber in the valve fills with disinfecting materialfrom said vessel air passes from said chamber into vessel 4 to take theplace of the disinfecting material discharged, and when said chamber ofthe valve discharges its load of disinfecting material it fills againwith air.

In the normal position of the valve the measuring-chamber of the valveis closed to the atmosphere. My disinfecting apparatus is thereforeparticularly adapted for using disinfecting materials which are volatileor which suffer loss or deterioration when exposed freely to the air andfor using disinfccting materials possessing anodor which it isnot'desired to disseminate. It will be obvious that this valve is notrestricted to use with liquids, but that it may be arranged to dischargeeach time into the flush-tank a no measured amount of powder or similarmaterial which will flow somewhat like water within the ves el t. essaryto make the ports ot' the valve proportionately larger than illustratedin Fig. 2.

It will be obvious that my invention is sust'eptible ol'nianyvariz'ttions and modifications ot' eonstrin-tion and arrangement of theparts, and l do not limit mysell' to the part ii-nlar ronstruet ionherein shown and deseribeil.

What-I claim is* 1. In a llnsh-tank, the combination ol Hush-tankprovided with means for varying the liquid-level therein, a. sealeddisinfectantrhamber monnted on the tank, a float in the tank and adisint'eetant-measnrer mounted on and operated by said tloat, saidmeasurer in its upward movement eonnnnnieating with the chamber and onits lower movement with the tank.

in sneh ease it may be ne(' 1 in a flush-tank, the combination of a[lush-tank provided with means for varying the liquid-level therein, asealed disinfectant- -han'iber mounted on the lush-tank, a float in thetank, atvalve-easing between tank and rhamber, a hollow valve-stemmounted on the float and fitting within the valve-casing and providedwith two perforations at dillerent levels, and means limiting thedownward travel of the stem, whereby in its upward travel the hollow ofthe stem communicates with the chamber and in its lower travel with theflush-tank.

In testimony whereof I atfiX my signature in the presence of twowitnesses. H. A. SILVERA. Q
